Description

La présente invention concerne un appareil pour la distribution de quantités prédéterminées de produits liquides et/ou pâteux ainsi qu'une installation pour la réalisation de préparations alimentaires utilisant ledit appareil.The present invention relates to an apparatus for dispensing quantities liquid and / or pasty products as well as an installation for the production of food preparations using said device.

De tels appareils sont connus de DE-4001 082-C1 et de US-A-5 645 195, qui dévoilent le préambule de la revendication 1.Such devices are known from DE-4001 082-C1 and from US-A-5,645,195, which discloses the preamble to the claim 1.

Elle s'applique notamment, mais non exclusivement, à la réalisation d'installations pour la fabrication de crêpes.It applies in particular, but not exclusively, to the realization facilities for making pancakes.

D'une façon générale, on sait que pour ce type d'application, on a déjà proposé des installations faisant intervenir :

  • une table de cuisson horizontale à une ou plusieurs plaques de cuisson,
  • un distributeur de pâte mobile au-dessus de la table de cuisson de manière à pouvoir déposer la pâte sur la (ou les) plaque(s) de cuisson, puis être ensuite écarté de ces dernières pour permettre à l'opérateur d'exécuter toutes les manipulations (en particulier le retournement) propres à la cuisson des crêpes.
In general, we know that for this type of application, we have already proposed installations involving:
  • a horizontal hob with one or more hobs,
  • a mobile dough dispenser above the hob so that the dough can be placed on the baking tray (s), and then moved away from them to allow the operator to perform all the handling (in particular the turning) specific to cooking the pancakes.

En particulier, le brevet WO95/20880, déposé au nom du Demandeur, propose un distributeur de pâte comprenant un réservoir réfrigéré dont le fond comprend un orifice de distribution commandé par un obturateur actionnable par une poignée latérale.In particular, patent WO95 / 20880, filed in the name of the Applicant, offers a dough dispenser including a refrigerated tank whose bottom includes a dispensing orifice controlled by an actuatable shutter by a side handle.

Cette solution s'avère particulièrement avantageuse et permet notamment d'accroítre les cadences de production des crêpes en réduisant à un strict minimum le temps nécessaire au dépôt de la pâte sur les plaques de cuisson.This solution is particularly advantageous and allows in particular to increase the production rates of pancakes by reducing to a strict minimum time required to deposit the dough on the baking sheets.

Néanmoins, elle présente un certain nombre d'inconvénients que l'invention se propose de supprimer :

  • Elle ne permet pas de doser avec précision les quantités de pâte déposée sur la plaque : Lors du dépôt, l'opérateur se base sur une évaluation de la quantité de pâte déposée sur la plaque pour refermer l'obturateur, les temps d'ouverture devant être modifiés en permanence en fonction de la quantité de pâte restant dans l'appareil. Outre le fait que cette évaluation est imprécise, elle présente l'inconvénient de ne pas prendre en compte la quantité de pâte qui s'écoule après la fermeture de l'obturateur. Cette opération de dépôt est donc imprécise et, néanmoins, accapare toute l'attention de l'opérateur qui ne peut donc pas, en parallèle, assurer une autre tâche (par exemple la surveillance d'une autre plaque de cuisson).
  • Il s'avère qu'après leur fermeture, l'obturateur et le conduit situé en aval de ce dernier laissent s'échapper des gouttes de pâte qui, du fait de la mobilité du doseur, viennent souiller la table de cuisson en différents emplacements. L'opérateur doit donc périodiquement nettoyer la table de cuisson en interrompant ainsi la cadence de production de crêpes.
  • Pour ces différentes raisons, le distributeur décrit dans le brevet WO95/20880 précité ne convient pas bien dans le cas où il est associé à d'autres distributeurs du même type, par exemple pour permettre à l'opérateur un choix de la pâte, voire même la distribution d'ingrédients ou de denrées d'accompagnement telles que, par exemple, de la crème, du chocolat fondu, de la sauce ...
Nevertheless, it has a certain number of drawbacks which the invention proposes to eliminate:
  • It does not make it possible to precisely dose the quantities of dough deposited on the plate: When depositing, the operator uses an evaluation of the quantity of dough deposited on the plate to close the shutter, the opening times before be permanently modified according to the quantity of dough remaining in the appliance. In addition to the fact that this evaluation is imprecise, it has the disadvantage of not taking into account the quantity of dough which flows after the closure of the shutter. This deposition operation is therefore imprecise and, nevertheless, monopolizes all the attention of the operator who cannot therefore, in parallel, perform another task (for example monitoring another hob).
  • It turns out that after they are closed, the shutter and the pipe located downstream of the latter allow drops of dough to escape, which, due to the mobility of the dispenser, contaminate the hob in different locations. The operator must therefore periodically clean the hob, thereby interrupting the rate of pancake production.
  • For these various reasons, the dispenser described in the aforementioned patent WO95 / 20880 is not well suited in the case where it is associated with other dispensers of the same type, for example to allow the operator a choice of dough, or even even the distribution of ingredients or accompanying foodstuffs such as, for example, cream, melted chocolate, sauce ...

En vue de supprimer tous ces inconvénients, l'invention propose un appareil de distribution du type susdit comprenant :

  • deux récipients superposés solidaires l'un de l'autre et communiquant l'un avec l'autre grâce à un orifice ménagé dans le fond du premier récipient, à savoir : un récipient supérieur, refermé par un couvercle, qui sert de réservoir de produit à distribuer et un récipient inférieur de plus petites dimensions, qui constitue un cylindre, dont le fond est muni d'un orifice de sortie ;
  • un piston qui coulisse avec étanchéité dans ledit récipient inférieur entre une position haute d'admission et une position basse fin de course de distribution, ce piston étant traversé par au moins un orifice et étant sollicité par des premiers moyens élastiques vers sa position haute d'admission ;
  • un clapet solidaire d'une tige d'actionnement du piston et mobile entre des positions d'ouverture et de fermeture dudit orifice, ce clapet étant sollicité par des seconds moyens élastiques vers sa position d'ouverture ;
  • une buse de distribution en communication avec le récipient inférieur grâce à un orifice équipé d'un siège d'étanchéité contre lequel est maintenu, en position normalement fermée, un obturateur logé dans ladite buse, sous l'effet d'un ressort ; ledit obturateur, normalement fermé s'ouvrant sous l'effet de la pression du produit contenu dans le récipient inférieur lorsque s'amorce la poussée du piston et
  • des moyens d'actionnement de la tige depuis l'extérieur desdits récipients, permettant d'obtenir successivement, à partir d'un état initial dans lequel le piston est en position haute d'admission, le clapet en position ouverte et l'obturateur en position fermée ;
  • la fermeture du clapet puis le déplacement du piston vers sa position fin de course de distribution, avec, simultanément ouverture de l'obturateur et distribution du produit, l'immobilisation du piston en fin de course avec fermeture de l'obturateur, l'ouverture du clapet ; puis
  • le retour du piston en position haute d'admission, avec, simultanément aspiration du produit contenu dans le récipient à l'intérieur du cylindre.
With a view to eliminating all these drawbacks, the invention proposes a dispensing device of the aforementioned type comprising:
  • two superimposed containers integral with each other and communicating with each other through an opening in the bottom of the first container, namely: an upper container, closed by a lid, which serves as a product reservoir to dispense and a lower container of smaller dimensions, which constitutes a cylinder, the bottom of which is provided with an outlet orifice;
  • a piston which slides in leaktightness in said lower receptacle between an upper intake position and a low distribution end position, this piston being traversed by at least one orifice and being urged by first elastic means towards its upper position admission;
  • a valve secured to a piston actuating rod and movable between the open and closed positions of said orifice, this valve being urged by second elastic means towards its open position;
  • a dispensing nozzle in communication with the lower container through an orifice fitted with a sealing seat against which is held, in the normally closed position, a shutter housed in said nozzle, under the effect of a spring; said shutter, normally closed, opening under the effect of the pressure of the product contained in the lower container when the piston thrust begins and
  • means for actuating the rod from the outside of said containers, making it possible to obtain successively, from an initial state in which the piston is in the high intake position, the valve in the open position and the shutter in closed position;
  • closing the valve and then moving the piston to its dispensing end-of-travel position, with simultaneously opening the shutter and dispensing the product, immobilizing the piston at the end of its travel with closing the shutter, opening the valve; then
  • the return of the piston to the high intake position, with, simultaneously, suction of the product contained in the container inside the cylinder.

Avantageusement, les susdits moyens d'actionnement pourront comprendre une tige qui s'étend coaxialement à l'intérieur du récipient supérieur et dont l'extrémité supérieure passe au travers d'un orifice prévu dans le couvercle. La partie inférieure de cette tige passe au travers de deux orifices coaxiaux respectivement prévus dans ledit clapet et dans ledit piston, des moyens de butée solidaires de la tige étant prévus pour limiter la course du clapet en position haute et la course du piston en position basse. Les moyens élastiques sollicitant le clapet vers sa position d'ouverture peuvent alors consister en un ressort hélicoïdal coaxial prenant appui sur le piston, ce ressort présentant une raideur plus faible que celle des moyens élastiques sollicitant le piston vers sa position haute d'admission.Advantageously, the above-mentioned actuation means may include a rod which extends coaxially inside the upper container and whose the upper end passes through an orifice provided in the cover. The lower part of this rod passes through two coaxial orifices respectively provided in said valve and in said piston, means for stop integral with the rod being provided to limit the stroke of the valve high position and the piston stroke in low position. Elastic means stressing the valve towards its open position can then consist of a coaxial helical spring bearing on the piston, this spring having a lower stiffness than that of the elastic means urging the piston towards its high intake position.

L'actionnement de la tige peut être alors assuré grâce à un levier de manoeuvre articulé par une extrémité sur le récipient supérieur et qui prend appui sur l'extrémité supérieure de la tige.The actuation of the rod can then be ensured by means of an operating lever articulated by one end on the upper container and which rests on the upper end of the rod.

Des modes d'exécution de l'invention seront décrits ci-après, à titre d'exemples non limitatifs, avec référence aux dessins annexés dans lesquels :

  • Les figures 1 et 2 sont deux coupes axiales d'un appareil pour la distribution de pâte à crêpes, au repos (figure 1) et en position fin de course de distribution (figure 2) ;
  • Les figures 3 et 4 représentent l'appareil en élévation (figure 3) et vu de dessus (figure 4) ;
  • La figure 5 est une coupe similaire à celle des figures 1 et 2, d'un appareil de distribution équipé de moyens de chauffage par bain-marie ;
  • La figure 6 est une représentation schématique d'une installation faisant intervenir plusieurs appareils de distribution disposés selon un montage en barillet.
    • Embodiments of the invention will be described below, by way of nonlimiting examples, with reference to the appended drawings in which:
  • Figures 1 and 2 are two axial sections of an apparatus for dispensing pancake batter, at rest (Figure 1) and in the dispensing end position (Figure 2);
  • Figures 3 and 4 show the device in elevation (Figure 3) and seen from above (Figure 4);
  • Figure 5 is a section similar to that of Figures 1 and 2, of a dispensing apparatus equipped with heating means by water bath;
  • Figure 6 is a schematic representation of an installation involving several distribution devices arranged in a barrel arrangement.

    • Dans l'exemple représenté sur les figures 1 et 2, l'appareil de distribution de pâte à crêpes comprend un récipient supérieur cylindrique 1 comportant :

    • une paroi extérieure cylindrique 2, par exemple en aluminium ou en acier inoxydable, dont la surface intérieure est revêtue d'une couche en matière thermiquement isolante 3 telle que par exemple du caoutchouc isolant et, coaxialement à ladite paroi extérieure,
    • une cuve intérieure amovible 4 à double parois qui délimitent un volume intercalaire 5 contenant une matière telle qu'un gel de refroidissement apte à stocker des frigories, cette cuve intérieure 4 étant destinée à recevoir la pâte à crêpes.
    In the example shown in FIGS. 1 and 2, the apparatus for dispensing pancake batter comprises a cylindrical upper container 1 comprising:
    • a cylindrical outer wall 2, for example made of aluminum or stainless steel, the inner surface of which is coated with a layer of thermally insulating material 3 such as for example insulating rubber and, coaxial with said outer wall,
    • a removable inner tank 4 with double walls which delimit an intermediate volume 5 containing a material such as a cooling gel capable of storing frigories, this inner tank 4 being intended to receive the pancake batter.

    Le récipient supérieur 1 est refermé dans sa partie supérieure par un couvercle circulaire 6, par exemple en aluminium ou en acier inoxydable, dont les bords 7 viennent en retour sur la face externe de la paroi extérieure 2.The upper container 1 is closed in its upper part by a cover circular 6, for example made of aluminum or stainless steel, the edges of which 7 come back on the external face of the external wall 2.

    Il est refermé par un fond 8 muni d'une cavité coaxiale 9 passant au travers de la paroi extérieure 2, de la couche isolante 3 et de la cuve intérieure 4. It is closed by a bottom 8 provided with a coaxial cavity 9 passing through the outer wall 2, the insulating layer 3 and the inner tank 4.

    Dans cette cavité 9 vient partiellement s'emboíter avec étanchéité un récipient inférieur 10 cylindrique, par exemple en aluminium ou en acier inoxydable, ouvert dans sa partie supérieure, dont le fond est constitué par un bouchon support de valve 11 venant se visser sur un filetage prévu sur la paroi extérieure cylindrique dudit récipient inférieur 10.In this cavity 9 partially fits with sealing a lower container 10 cylindrical, e.g. aluminum or stainless steel, open in its upper part, the bottom of which consists of a valve support plug 11 coming to be screwed onto a thread provided on the cylindrical outer wall of said lower container 10.

    Ce récipient inférieur 10, dont les dimensions sont très inférieures à celles du récipient supérieur 1, constitue un cylindre dans lequel coulisse avec étanchéité un piston 12, l'étanchéité est ici assurée par un joint torique qui équipe la jupe cylindrique du piston 12.This lower container 10, the dimensions of which are much smaller than those of the container upper 1, constitutes a cylinder in which slides with sealing a piston 12, the seal is ensured here by an O-ring which equips the skirt cylindrical piston 12.

    Ce piston 12, qui présente une série d'orifices ou perçages traversants 13 permettant le passage de la pâte d'un récipient 1 à l'autre 10, est sollicité par des premiers moyens élastiques (14) sous forme d'un ressort hélicoïdal logé dans le récipient inférieur 10 et prenant appui sur le bouchon 11.This piston 12, which has a series of through holes or holes 13 allowing the passage of the dough from one container 1 to the other 10, is stressed by first elastic means (14) in the form of a spring helical housed in the lower container 10 and bearing on the plug 11.

    Ce bouchon 11 comprend, quant à lui, un orifice central débouchant dans un manchon cylindrique coaxial 15 refermé par un écrou borgne 16 dont le fond est muni d'un orifice de sortie coaxial 17.This plug 11 comprises, for its part, a central orifice opening into a coaxial cylindrical sleeve 15 closed by a cap nut 16 whose bottom has a coaxial outlet 17.

    L'orifice central est équipé d'un siège annulaire S sur lequel peut venir en contact étanche une bille B sollicitée par un ressort hélicoïdal 18 logé dans le manchon 15 et prenant appui sur le fond de l'écrou 16.The central opening is equipped with an annular seat S on which can come in sealed contact a ball B urged by a helical spring 18 housed in the sleeve 15 and bearing on the bottom of the nut 16.

    L'actionnement du piston 12 est assuré par une tige 20 qui s'étend coaxialement au récipient 1 et dont la partie supérieure traverse le couvercle 6 et se termine au-dessus de ce dernier par une noix 21 sur laquelle vient en appui un levier 22 articulé par l'une de ses extrémités à la paroi extérieure du récipient et portant une poignée 23 à son autre extrémité. The piston 12 is actuated by a rod 20 which extends coaxially with the container 1 and the upper part of which crosses the cover 6 and ends above the latter with a nut 21 on which comes in support a lever 22 articulated by one of its ends to the outer wall of the container and carrying a handle 23 at its other end.

    Dans sa partie inférieure, la tige 20 présente un tronçon 24 de plus faible diamètre passant successivement au travers d'un orifice central coaxial d'un clapet circulaire 25 et d'un orifice central coaxial du piston 12.In its lower part, the rod 20 has a shorter section 24 diameter passing successively through a coaxial central orifice of a circular valve 25 and a central coaxial opening of the piston 12.

    Le clapet 25 et le piston 12 sont donc montés coulissants sur le tronçon 24. La course du piston 12 est limitée vers le bas par une butée constituée ici par un écrou à ailettes 26 venant se visser sur un filetage réalisé sur l'extrémité inférieure du tronçon 24.The valve 25 and the piston 12 are therefore slidably mounted on the section 24. The stroke of piston 12 is limited downwards by a stop constituted here by a wing nut 26 screwing onto a thread made on the end lower section 24.

    La course du clapet 25 est limitée vers le haut par le décrochement 27 formé entre la tige 20 et le tronçon 24.The stroke of the valve 25 is limited upwards by the recess 27 formed between the rod 20 and the section 24.

    Le piston 12 et le clapet 25 sont sollicités vers leurs butées respectives par des seconds moyens élastiques 28 sous forme d'un ressort hélicoïdal de raideur inférieure à la raideur des premiers moyens élastiques 14.The piston 12 and the valve 25 are biased towards their respective stops by second elastic means 28 in the form of a helical spring of stiffness less than the stiffness of the first elastic means 14.

    Par ailleurs, les déplacements de la tige 20 vers le bas sont limités grâce à une butée réglable annulaire 29, mobile le long de la partie de la tige 20 qui dépasse au-dessus du couvercle 6 et qui, en fin de course vers le bas, vient en appui sur ce dernier. Le blocage en position de la butée 29 sur la tige est obtenu au moyen d'une vis pointeau 30 qui se visse dans un perçage taraudé de manière à venir en appui sur la tige 20 en assurant un blocage. La manoeuvre de cette vis 30 est assurée grâce à une tête moletée.Furthermore, the downward movements of the rod 20 are limited thanks to a adjustable annular stop 29, movable along the part of the rod 20 which protrudes above cover 6 and which, at the end of its downward travel, comes support on the latter. The blocking in position of the stopper 29 on the rod is obtained by means of a needle screw 30 which is screwed in a threaded hole of so as to come to bear on the rod 20 while ensuring a blocking. The process of this screw 30 is ensured by means of a knurled head.

    Le remplissage du récipient 1 s'effectue grâce à un orifice prévu dans le couvercle 6 et refermé par un bouchon 31.The filling of the container 1 is carried out through an orifice provided in the cover 6 and closed by a plug 31.

    Le couvercle 6 est en outre équipé d'un thermomètre 32 dont la sonde 33 plonge à l'intérieur de la cuve 4 et d'un compteur classique 34 effectuant un comptage des manoeuvres de la tige 20. The cover 6 is further equipped with a thermometer 32 including the probe 33 plunges inside the tank 4 and a conventional counter 34 performing a counting of the maneuvers of the rod 20.

    Dans cet exemple, l'appareil de distribution est monté à l'extrémité d'une potence 35 dont le support est pivoté autour d'un axe vertical XX'. L'appareil peut donc être déplacé au gré de l'opérateur, par exemple d'une plaque de cuisson à une autre.In this example, the dispensing device is mounted at the end of a bracket 35 whose support is pivoted about a vertical axis XX '. The device can therefore be moved at the discretion of the operator, for example a plate cooking to another.

    D'une façon analogue, l'appareil de distribution pourrait être monté coulissant le long d'un rail de manière à pouvoir desservir un nombre illimité de plaques de cuisson.Similarly, the dispensing device could be slidably mounted along a rail so that it can serve an unlimited number of plates Cooking.

    Le fonctionnement de cet appareil est alors le suivant :The operation of this device is then as follows:

    Dans une phase préalable, l'opérateur ôte la cuve intérieure 5 et la place dans un congélateur pour qu'elle accumule la quantité de frigories nécessaire pour maintenir la pâte qu'elle sera amenée à contenir, à une température inférieure à un seuil déterminé. Avantageusement, cette phase préalable pourra s'effectuer la nuit.In a preliminary phase, the operator removes the inner tank 5 and places it in a freezer so that it accumulates the amount of frigories necessary to maintain the dough it will contain, at a temperature below a determined threshold. Advantageously, this preliminary phase can be carried out the night.

    Une fois cette phase préalable exécutée, l'opérateur réassemble l'appareil de distribution et remplit la cuve 4 de pâte grâce à l'orifice du couvercle 6.Once this preliminary phase has been carried out, the operator reassembles the distribution and fills the tank 4 with dough through the hole in the cover 6.

    Sous l'effet des premiers moyens élastiques 14, le piston 12 se trouve en position haute d'admission, tandis que le clapet 25 sollicité par les seconds moyens élastiques 28 est en position ouverte, en butée sur le décrochement d'alésage 27. Le piston 12 vient en outre en butée et est retenu sur l'écrou à ailettes 26. Dans cette osition, la pâte introduite dans le récipient 1 vient remplir, grâce aux orifices 13, le récipient 10. La bille B sollicitée par le ressort obture l'orifice délimité par le siège S, de sorte que la pâte demeure à l'intérieur des deux récipients 1, 10.Under the effect of the first elastic means 14, the piston 12 is in the high intake position, while the valve 25 urged by the second elastic means 28 is in the open position, in abutment on the bore recess 27. The piston 12 further abuts and is retained on the wing nut 26. In this position, the paste introduced into the container 1 comes to fill, thanks to the orifices 13, the container 10. The ball B biased by the spring closes the orifice delimited by the seat S, so that the dough remains inside the two containers 1, 10.

    Lorsque l'opérateur veut déposer une dose de pâte, par exemple sur la table de cuisson, il manoeuvre le levier 22 de manière à déplacer la tige 20 vers le bas jusqu'à ce que la butée réglable 29 vienne en appui sur le couvercle 6. Bien entendu, la course de la tige 20 qui correspond à la dose de pâte déposée est réglée selon le désir de l'opérateur grâce au réglage de la position de la butée 29 sur la tige 20.When the operator wants to deposit a dose of dough, for example on the table cooking, it operates the lever 22 so as to move the rod 20 downwards until the adjustable stop 29 comes to bear on the cover 6. Good heard, the stroke of the rod 20 which corresponds to the dose of paste deposited is adjusted as desired by the operator by adjusting the position of the stop 29 on rod 20.

    Dans une première fraction de la course de déplacement vers le bas de la tige 20, le clapet 25 est actionné par le bas jusqu'à ce qu'il vienne en contact étanche sur le piston 12 en bouchant les orifices 13. Au cours de cette première fraction de course, les seconds moyens élastiques 28 subissent un écrasement mais n'exercent pas sur le piston 12 une force suffisante pour le déplacer significativement en raison de la raideur des premiers moyens élastiques 14.In the first fraction of the downward movement of the rod 20, the valve 25 is actuated from below until it comes into tight contact on the piston 12 by plugging the orifices 13. During this first fraction of a stroke, the second elastic means 28 undergo a crushing but do not exert on the piston 12 enough force to move it significantly due to the stiffness of the first elastic means 14.

    Dans une seconde fraction de course de la tige, le piston 12 est entraíné par le clapet 25 contre l'action des premiers moyens élastiques 14, les orifices 13 se trouvant obturés du fait de l'appui du clapet 25 sur le piston 12.In a second fraction of the stroke of the rod, the piston 12 is driven by the valve 25 against the action of the first elastic means 14, the orifices 13 being closed off from the presses the valve 25 against the piston 12.

    La pression exercée sur la pâte par le piston 12 se répercute sur la bille B qui, en comprimant le ressort 18, s'écarte de la portée S.The pressure exerted on the dough by the piston 12 has repercussions on the ball B which, by compressing the spring 18, moves away from the range S.

    La pâte peut donc s'écouler par le manchon 15 et l'orifice 17, de la façon illustrée sur la figure 2. L'écoulement de la pâte cesse en même temps que cesse le déplacement de la tige 20, soit que la butée 29 est arrivée au contact du couvercle 6, soit par suite d'une interruption volontaire de l'action de l'opérateur.The dough can therefore flow through the sleeve 15 and the orifice 17, in the manner illustrated in Figure 2. The flow of dough stops at the same time as stops the movement of the rod 20, that is to say that the stop 29 has come into contact of cover 6, either as a result of a voluntary interruption of the action of the operator.

    Dans ce cas, la bille B qui ne subit plus la pression de la pâte est repoussée par le ressort sur la portée S. De ce fait, l'écoulement de la pâte s'interrompt tandis que la quantité de pâte demeurant dans le manchon 15 demeure prisonnière sous l'effet de la tension superficielle et de la pression atmosphérique. De ce fait, le problème résultant des gouttes de pâte tombant sur la table de cuisson au cours des manipulations de l'appareil se trouve résolu.In this case, the ball B which no longer undergoes the pressure of the dough is repelled by the spring on the bearing S. As a result, the flow of the dough is interrupted while that the quantity of dough remaining in the sleeve 15 remains trapped under the effect of surface tension and atmospheric pressure. From this done, the problem resulting from dough drops falling on the hob during handling of the device is resolved.

    Lorsque l'opérateur relâche la poignée 23, le clapet 25 maintenu sur l'étagement 27 de la tige 20 par les seconds moyens élastiques 28, accompagne le mouvement de la tige 20 vers le haut. Parallèlement, le piston 12 remonte sous l'effet des premiers moyens élastiques 14 et/ou de l'écrou à ailettes 26.When the operator releases the handle 23, the valve 25 held on the stepping 27 of the rod 20 by the second elastic means 28, accompanies the movement of the rod 20 upwards. At the same time, the piston 12 rises under the effect of the first elastic means 14 and / or the wing nut 26.

    Lors de sa remontée, le clapet se trouve soulevé par les seconds moyens élastiques 28, la pâte contenue dans le récipient se trouve aspirée dans le récipient inférieur, à travers les orifices 13.During its ascent, the valve is raised by the second elastic means 28, the dough contained in the container is sucked into the lower container, at through the holes 13.

    En fin de course d'admission (position illustrée figure 1), le récipient 10 est à nouveau rempli de pâte et l'appareil est prêt pour une nouvelle manoeuvre.At the end of the intake stroke (position illustrated in FIG. 1), the container 10 is at again filled with dough and the appliance is ready for a new operation.

    Grâce à la matière contenue dans la cuve intérieure amovible, la pâte contenue dans le récipient 1 demeure dans une plage de température prédéterminée garantissant sa conservation.Thanks to the material contained in the removable inner tank, the dough contained in container 1 remains within a predetermined temperature range guaranteeing its conservation.

    L'invention ne se limite pas au mode d'exécution précédemment décrit, ainsi, dans le cas où le produit à distribuer doit demeurer à une température supérieure à la température ambiante, ce qui est le cas, par exemple, du chocolat fondu, la couche en matière isolante 3 pourra être remplacée par une couche incluant des moyens de chauffage et/ou de maintien à une température supérieure à la température ambiante.The invention is not limited to the embodiment described above, thus, if the product to be dispensed must remain at a temperature higher than room temperature, which is the case, for example, melted chocolate, the layer of insulating material 3 may be replaced by a layer including means for heating and / or maintaining a temperature higher than room temperature.

    Ainsi, dans l'exemple représenté sur la figure 5, la couche 3 a été remplacée par une couche 3' en caoutchouc chauffant alimentée par un circuit d'alimentation électrique 40 connectable au secteur et incluant un thermostat 41. Dans ce cas, il est possible d'utiliser une cuve 4' similaire à la cuve 4, le gel jouant alors, d'une façon surprenante, le rôle d'un bain-marie.Thus, in the example shown in Figure 5, layer 3 has been replaced by a 3 'layer of heating rubber supplied by a circuit power supply 40 connectable to the mains and including a thermostat 41. In this case, it is possible to use a tank 4 'similar to tank 4, the gel then surprisingly playing the role of a double boiler.

    Un avantage important des appareils précédemment décrits consiste en ce qu'en raison de leur aptitude à délivrer des produits froids ou chauds et de leur ergonomie, ils s'intègrent à des installations telles que celle représentée schématiquement figure 6 qui comprend quatre distributeurs D1 à D4 assemblés côte à côte à la façon d'un barillet. Cet ensemble de distributeurs D1 à D4 est monté pivotant autour d'un axe vertical V1 à l'extrémité d'une potence P dont l'autre extrémité pivote autour d'un axe vertical V2 porté par une structure fixe telle que, par exemple, un montant vertical MV de manière à pouvoir se déplacer au-dessus d'une table de cuisson TC comprenant ici deux plaques chauffantes CH1, CH2.An important advantage of the devices described above is that, because of their ability to deliver cold or hot products and their ergonomics, they can be integrated into installations such as the one shown diagrammatically in FIG. 6 which includes four distributors D 1 to D 4 assembled side by side like a barrel. This set of distributors D 1 to D 4 is pivotally mounted around a vertical axis V 1 at the end of a bracket P whose other end pivots around a vertical axis V 2 carried by a fixed structure such that , for example, a vertical upright MV so as to be able to move over a hob TC comprising here two hot plates CH 1 , CH 2 .

    Les pivoteries prévues aux extrémités de la potence P peuvent comprendre un système de crantage facilitant le centrage des distributeurs D1 à D4 sur les plaques chauffantes CH1, CH2.The pivotings provided at the ends of the bracket P may include a notching system facilitating the centering of the distributors D 1 to D 4 on the heating plates CH 1 , CH 2 .

    Grâce à ces dispositions, l'opérateur peut effectuer un choix entre plusieurs compositions de pâtes (par exemple au froment ou au sarrasin) et/ou plusieurs sortes de garnitures (chocolat fondu, crème).Thanks to these provisions, the operator can choose between several pasta compositions (e.g. wheat or buckwheat) and / or more kinds of fillings (melted chocolate, cream).

    Ce résultat est obtenu avec une capacité de production accrue (possibilité d'accroissement des cadences de production) et avec une meilleure qualité des produits (homogénéité de la production, hygiène).This result is obtained with an increased production capacity (possibility increasing production rates) and with better quality of products (consistency of production, hygiene).

    Bien entendu, dans une version industrielle, l'appareil pourra comprendre un actionneur hydraulique ou pneumatique pour la commande des déplacements de la tige des distributeurs. Of course, in an industrial version, the device may include a hydraulic or pneumatic actuator for movement control valve stem.

    De même, les ensembles de distributeurs pourront être montés coulissants le long d'un rail de manière à pouvoir être déplacés au-dessus d'un nombre indéterminé de plaques chauffantes.Likewise, the distributor assemblies can be slidably mounted on along a rail so that it can be moved over a number indeterminate hot plates.
